Ouch...no, she's alright.
Paula Badosa hits the deck stretching for a wide one and for a second it appaears like she's rolled her ankle.
But the Spaniard is quickly back to her feet and even sees the funny side, gesturing to the crowd that she dived.
Sabalenka holds to love.

As the roof closed, there was an army of ball kids furiously mopping the court with towels. A slippery surface is no good to anyone.
Any moisture left will dry quickly, I'm sure. The temperature indoors has gone up a few centigrade.
Imagine that would allow both players to belt the ball with a bit of extra oomph.
Oh, and a reminder... once shut, the roof stays shut.
